I have not gone to the ER for my pain. My dr usually gives me something over the phone. I pray your pain levels go down, and you get a nights rest. Hang in there. I know a few of my friends have gone to the ER and they dont get taken seriously because the nurses don't know what RSD is. I dont know if pain medication helps your pain?? It makes mine worse most of the time. May God comfort you and take your pain away.
